Meghan has recalled the 'surreal' day the Queen helped her pick out her wedding tiara at Buckingham Palace
The Duchess of Sussex, 37, said the Queen Mary Diamond Bandeau was the 'perfect' choice, describing how she wanted her bridal look to be 'incredibly timeless' yet 'still modern'
She spoke about picking out the tiara in a special recording for a new exhibition at Windsor Castle, where the tiara is on display alongside her stunning Givenchy wedding gown
Meghan also revealed Prince Harry, 34, accompanied her to Buckingham Palace to pick out the tiara, although her now husband admitted 'I shouldn't have really been there'
The Duchess said: 'When it came to the tiara on the day, I was very fortunate to be able to choose this gorgeous art deco style bandeau tiara
'Harry and I had gone to Buckingham Palace to meet with Her Majesty The Queen to select one of the options that were there, which was an incredibly surreal day as you can imagine
'And that was the one that, I think, as we tried them on, stood out.' Speaking about the tiara she eventually chose, she continued: 'I think it was just perfect because it was so clean and simple - and also to that point, an extension of what Clare and I had been trying to do with the dress which was have something that could be so incredibly timeless but still feel modern
' Harry said that 'without question' the Queen Mary Diamond Bandeau the one that looked best on Meghan
' '[I]t's every girl’s dream to be able to try on a tiara. Funnily enough, [it was] the one that suited the best, the one that looked the best on you without question
'I shouldn’t have really even been there, but such an incredible loan by my grandmother, it was very sweet…' Queen Mary's Diamond Bandeau went on display at Windsor Castle today as part of the A Royal Wedding: The Duke and Duchess of Sussex exhibition, which will run into January
In a recording made for visitors to the exhibition, the Duke and Duchess also discussed the amount of planning that went into the May 19 wedding
Meghan said: 'A great level of detail went into the planning of our wedding day. We knew how large the scale of the event would be, so in making choices that were really personal and meaningful, it could make the whole experience feel intimate
Harry added: 'I chose the frock coat as a uniform, with permission from my grandmother, because I think it's one of the smartest Household Cavalry uniforms
It's one of my favourites, and I was very fortunate to be able to wear that on the day
'Prince George and Princess Charlotte's royal wedding outfits go on display today as part of the new Windsor Castle exhibition, along with a replica of Harry's frock coat
Members of the public will be given a closer view of George's mini version of the coat, created by Savile Row tailors Dege & Skinner, which has his initials embroidered in gold thread on the shoulder straps
Meanwhile Charlotte's bridesmaid dress by Givenchy features short puff sleeves and a double silk ribbon at the waist, tied in a bow at the back
Her white leather shoes were made by Aquazurra and embroidered with her initials and the wedding date
A replica of The Duchess of Sussex's bridal bouquet made from artificial flowers has been created for the exhibition
Meghan's something borrowed: Which tiara did she wear? Meghan's sparkling tiara is Queen Mary's Diamond Bandeau, which has been loaned to her by Harry's grandmother the Queen
Royal brides are traditionally loaned priceless heirlooms to wear on their wedding day
Meghan could have chosen the Spencer tiara - famously worn by Harry's later mother Diana, Princess of Wales when she married the Prince of Wales in 1981
But Meghan has instead selected this little known piece, which features a magnificent floral-shaped suspended brooch in the centre made of a large round diamond surrounded by nine smaller circular diamonds
It was specifically made for the Queen's grandmother Queen Mary in 1932 to accommodate the detachable brooch, which was given to Mary as a wedding present in 1893 by the County of Lincoln
The bandeau is a flexible band of 11 intricate glittering sections, pierced with interlaced ovals and pave set with large and small brilliant diamonds
The bandeau and the brooch were bequeathed by Queen Mary to her granddaughter the Queen on her death in 1953
